In the earlier days, the educators could deliver lectures to a group of students in one classroom but now with the boom in technological advancement, it is getting harder to state reasons for their physical presence. It is agreed that it is difficult for justifying the reasons to be physically present in such gatherings while there is an alternative option, the internet.
The primary reason for this is that the time flexibility of online classes. The scholars might schedule their own time to learn the subjects taught since the digitalized academic materials facilitate the saving for reviewing it later. To illustrate, the tutors could either record their lessons and upload in YouTube or send links to tutees' email address or even post in students' common login page. These easily accessible options were not under limelight until the emergence of the internet.
Another connected reason is the possibility to access many experts at one time. Even if the novice is about to attend the lecture directly, there is less chance for him to meet many educators at the same place but with recent application software like Google hangout, it has become facile to gather knowledge from different people of the same field of study.
To conclude, while there is a better option to choose from with the advent of technology, learners tend not to get inclined to other choices. Unless there is a mandatory need to get enrolled for the lectures in person, undoubtedly they prefer online classes. My personal viewpoint is that this way of updated learning has become more useful because of the ease provided to manage their time properly. Thus e-classrooms and tuitions are better to be preferred by the students of this modern era.
